Mexican Hash Brown Breakfast Casserole: Step-by-Step Guide

Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures that your casserole bakes evenly and reaches that perfect golden-brown finish.
Step 2: Prepare the Hash Browns
Arrange the frozen hash brown patties in a single layer at the bottom of your greased 9×13-inch baking dish. Make sure they cover the entire base for that delicious crispy layer.
Step 3: Cook the Sausage
In a skillet over medium heat, cook the sausage until it’s browned and fully cooked, about 5-7 minutes. Break it up into small pieces as it cooks for even distribution in the casserole.
Step 4: Mix the Egg Mixture
In a large mixing bowl, whisk together the eggs, milk, and taco seasoning until well combined. This will be the creamy base that binds everything together.
Step 5: Layer Your Ingredients
Once the sausage is cooked, spread it evenly over the hash brown layer in the baking dish. Pour the egg mixture over the sausage and hash browns, making sure it’s evenly coated.
Step 6: Add the Salsa and Cheese
Spoon the salsa over the top, spreading it out for maximum flavor. Then, sprinkle the shredded cheddar and Monterey Jack cheeses evenly across the top.
Step 7: Bake the Casserole
Place the casserole in the preheated oven and bake for 45-50 minutes, or until the eggs are set and the top is golden and bubbly.
Step 8: Let It Cool and Serve
Once baked, remove the casserole from the oven and let it cool for about 10 minutes. This will help it set up a bit more, making it easier to slice and serve. Cut into squares and enjoy!
How to Make It Lighter

- Use turkey or chicken sausage instead of pork sausage for a leaner option.
- Replace whole milk with skim milk or a plant-based milk alternative.
- Opt for reduced-fat cheese varieties to cut down on calories.
- Add more vegetables like bell peppers, onions, or spinach to increase the nutritional value.
